Artificial Breeding and Breeding Techniques
Yellow-tailed pheasants are commonly found in rivers, lakes, and other broad bodies of water. They are plentiful and sublime. They are adapted to livelihoods and have mixed feeding habits. They often use detritus, diatoms, green algae, blue-green algae aquatic insects, shrimp, zooplankton, and other foods. Yellow Tai Mei Mi can reach more than 400 millimeters. It is a common small and medium-sized fish in rivers, and its natural production is also large. In the last year, Meili had a body length of 150-200 mm, a weight of 30-60 grams, and a second year of 200-250 grams. First, the artificial breeding of yellow-tailed tadpoles In the natural water body, the yellow-tailed Miphilus is mature in the second age and can also breed spawning in the pond. From April to June each year, the temperature of the sunny water rises above 20°C after the rain. The male and female fish swim to the side of the plants with water currents, chasing each other to lay eggs. The eggs are sticky and attached to the gravel plants. The eggs can pass for about 1 week. Hatching seedlings. 1. Collection and cultivation of pro-fish species: Pro-fish species collection should be concentrated in the winter fishing season. Individuals with large individuals, obvious sexual maturity, and robust disease-free, bright color are preferred. The cultivation pond is about 0.5-1 mu and the water depth is 1.5 meters. The amount of sub-fertilizer Mu is 80-100 kg. The cultivation is mainly to improve the water quality. Some artificial feeds can be added to meet the needs of fish nutrition. Pre-pay attention to adequate water supply. 2, artificial oxytocin: oxytocin bred abdominal soft, inflated, anal swelling, genital hole is better, the pituitary gland as oxytocic agent, 2-3 pituitary per kilogram, male half fish, male and female ratio 1:1 Artificial insemination can also be used, artificial water incubating after de-bonding. The time of injection is early in the evening, and spawning can be performed in the early morning of the next morning. 3. Incubation management: The suitable temperature for hatching egg of yellow-tailed pheasant eggs is 18-25°C. After about 20 days, the fish eggs will hatch out of seedlings after 7 days, and the yolk sac will disappear. When the body has a little pigment, it will be transferred to fry. Second, the culture of the yellow tail 1, seed cultivation techniques: generally take a single, shallow water seedlings, lagging behind and fertilizer, gradually deepen the water level, timely screening, dilute the pool to raise the method of cultivation, the lower pool density control in 200,000 / acre, after 5 days After fertilization, it will be cultivated in about 7 days. When the fry reaches 1.5 cm, it can be raised and kept in small ponds through large screens, and it will be transferred to deep pool farming with a density of 50,000-60,000 tails per acre. After more than 10 days, fry breeding will be completed. stage. 2. Fish species cultivation: Currently, polyculture methods are mostly used because they are not subject to other fish restrictions, such as 5000-6000 acres of acre, 5 months of culture, and 5 grams at the end of the year. This method is currently used less frequently. 3, adult fish farming: mainly in large-scale stocking and pond polyculture. (1) Large water surface stocking: lakes and reservoirs average 100-200 mu per mu, and can reach 40-60 grams at the end of the year. Without affecting the growth of other fish, the net yield per mu is 5-10 kg. 30-50 yuan. (2) Polyculture in ponds: 1000-1200 acres per acre, based on fish pond fat, food apology determined. Generally, 25-50 kilograms per mu are produced. There is a certain symbiotic relationship between the yellow-tailed migratory plague and other fishes, which can make full use of residual organic matter in water and organic organisms to reduce the occurrence of other fish diseases.
